Round

This node rounds a number to the nearest integer.

The Round node performs standard mathematical rounding.

The Round node takes a numeric input and rounds it to the nearest integer. Values with a fractional part of .5 or greater round up, while less than .5 round down. For example, 4.5 becomes 5, 4.4 becomes 4.

Inputs

Input

Data	Description
Value	The number to round. Default: 0.

Actions

Signal	Description
Do	Triggers the calculation. The result is updated only when this signal is received.

Outputs

Data

Data	Description
Rounded Value	The rounded integer result.

Signals

Signal	Description
Done	Triggered when the calculation is successfully completed.

Usage

Use this node for general-purpose rounding where you want the closest whole number.

Example Use Cases

1. UI Display: Showing a clean integer score instead of a float.
2. Snapping: Snapping an object position to the nearest grid line.
3. Statistics: Rounding averages to whole numbers.

Detailed Behavior

1. Validation:
   • Input must be a valid number.
   • Input and Result must be within ±1,000,000,000,000.
2. Calculation:
   • Uses Math.round().
   • Triggered only by the Do signal.
3. Error Handling:
   • If the result exceeds the allowed range, an error is logged and Done is not signaled.

Troubleshooting

• Midpoint Rounding: Math.round() rounds .5 up towards positive infinity. -4.5 becomes -4, and 4.5 becomes 5.
